Ibycus, Fragment 299 (from Scholiast on Apollonius Rhodius) (trans. Campbell, Vol. Greek Lyric III) (C6th B.C.) :
"There are many stories about the girdle [that Herakles was sent to fetch]: some say it belonged to Hippolyta, others to Deilyka. Ibykos is alone in saying that it belonged to Oiolyka (Oeolycus), daughter of Briareos (Briareus)."
